To all whom zit may concern:

The present invention is designed to expe dite and cheapen the process of manufacturing boots and shoes.

The invention consists in a new procedure introduced in advance of the operations by which the lasting of a boot or shoe is effected and involving a'succession of steps which assemble together certain of the prepared portions of a boot or shoe and secure them together in a shape and condition which facilitate the subsequent work. In substance the steps of the said new procedure involve assembling together in proper relations with one another the inner sole, lining, counter, and 5 upper of a boot or shoe and securing these parts together at the heel only. The performance of these steps places the specified parts of a boot or shoe in a condition which enables them to be taken by the laster and be by him 3 immediately fitted and adjusted to a last and then to have the lasting operations performed in connection therewith. The said steps admit of being carried into effect almost exclusively by hand, although it will be obvious that in practice the assistance of mechanical means will be utilized as far as possible. The precise nature of the said mechanical means is not material so far as the new method involving the invention is concerned.

The drawings of the present case show and the descriptive portion of the present specification describes mechanical aids which may be employed in carrying the method into effect if deemed advisable. The said mechanical aids are made the subject of claims in the United States Letters Patent granted April 30, 1901, in the name of Charles \V. King, for improvement in machines for assembling inner soles, linings, and counters of boots and shoes, No. 672,624, of which this case is a di- 5 vision.

In the drawings, Figure 1 shows in front elevation the machine forming the subject of the pending patent aforesaid and which may be employed, if desired, in carrying the present invention into efi'ect. Fig. 2 shows in side elevation the upper part of the said machine. Fig. 3 shows the said machine in plan. Figs. 4 and 5 are sectional views of the upper portion of the machine on planes at right angles to each other. Figs. 6 and 7 are detail views in section, respectively showing the pin-carrying plate and pins in the opposite positions thereof. Figs. 8, 9, 10, and 11 are views illustrating the steps of the method 5 in which the invention resides.

In the drawings, A represents a standard or column having a base B, on which are supportedand carried the various operating parts of the machine.

C is a horizontal plate which is secured on the upper end of the standard A by screws D. This plate C is shaped in outline to conform generally to that of the edge of the heel portion of an inner sole, as shown in plan in Fig. 7 5 3, and the exterior of the standard for a short distance below the plate is shaped correspondingly.

Under the plate C is a recess or chamber E, and in this chamber is a horizontal plate G, arranged to be moved up and down therein. The said plate G is secured by a central screw (Z on the upper end of a spindle H, which latter passes freely down through a vertical passage 0 in the transverse thickness 3 5 a of the standard, its lower end extending into a chamber J in the column, below the portion a, and being connected by'a link K to an arm h of a lever L, pivoted on a cross pin or screw m in the standard and having ahan- 9 die M extending out through the front opening of the chamber J for the actuation thereof. On swinging the handle M of lever L down the plate Gr is moved up, as shown in Fig. 7 in section, and on swinging the said handle up the plate is moved down to its normal position, as shown in Fig. 6.

Secured in the plate Ur, around its curved edge, is a series of vertical pointed-pins N, of a length enabling them when the plate is in its normal or depressed position, as shown in section in Figs. 4 and 6, to project up into openings 11. in the fixed plate C. When this plate G is moved up into the position shown in section in Fig. 7, the pins will project above the plate, as shown.

P is an arm extending through an opening "/in the side of the standard into the chamber J of the standard and pivotally mounted within said chamber. At its upper end said arm has a right-angled projecting portion a, provided with a plate R of substantially the same outline as the plate C. but preferably a little larger. The inner end of this arm P is formed with a transverse slot '0, receiving a block S, through which the pivotal pin t extends, the arm being adapted to slide lengthwise on said block and the block having a pin 20, which projects up into a socket 3 lin the arm. A springs in said socket is compressed between the upper end of said pin and the inner end of a screw T, as shown more particularly in Fig. 5.

The inner end of the arm P has on its edge a toothed segment U, the lower portion of which is concentric to the pin 26, while its upper portion extends in a straight or vertical line. as at a, Fig. 5. The said segment U engages with a vertical rack-bar V, adapted to slide up and down in a guideway b in the inside of the column and connected by a pitman-rod Y to a treadle A, Fig. 1.

B is a spiral spring connected by one end thereof to the treadle and by its other end to the lower end of the rack-bar V, as shown in Fig. 1. Pressing down the treadle A pulls down the raek-bar V, which by its engagement with the segment-gear on .the arm P first swings the arm forward and toward the standard into a vertical position, carrying its plate R into position over and a little above the plate C on the upper end of the column, after which the engagement of the rack-bar with the gear-teeth on the straight portion A of the arm in the continued downward movement of the treadle and the rack-bar causes the arm P to move vertically downward until its place R is close to or bears upon the plate. The downward movement of the arm compresses the spring 2, the arm sliding or moving over its pivot-block S. When the treadle is allowed to rise, the rack-bar moves up, carrying with it the arm P, and as the rack-bar engages with the segmental gear in its continued upward movement it swings the arm P outward into its normal position, as shown in Figs. 1, 3, and 5. Through the plate R,

near its edge, is a series of holes or openings e, which when the arm is swung up into its true vertical position register with the holes in the plate C, so that when the plate R is in position over the column-plate, if then the pinplate G is moved up, the pins N extending through the holes in the plate C will also enter more or less the openings or holes 01 in the plate R.

D is an arm on the side of the column at right angles to the plate-arm P, pivoted upon a cross-pin E and having an angular extension w, in which is a slot F, through which passes a cross-pin G, mounted in the forked inner arm of a lever H, pivoted at 1 between two lugs a on the outside of the column and having a handle 6 for the operation thereof. The lugs to are provided on a block Q, secured to the standard by the pivot-screw t of the arm P, the said screw passing through a vertical slot (Z in the block. The block rests on a vertical screw 6 screwing up through a lug f of the standard. by which the height of the lugs can be adjusted to regulate the height of the arm D for its work. Attached to the upper end of this arm D are two arms J", projecting forward and having their inner edges curved, as shown in Figs. 3, 10, and 11. Pivoted at to each end of these arms J are extensions or pieces K, which project still farther forward and are adapted to freely swing to and from each other on their respective pivots. To press them toward each other, each arm K has arranged in connection therewith a spring 72?. which bears against its outer side. Connected to each outer end of each of these arms by a pivot L is a chain or flexible band M, which extends back and is freely disposed in between the arms K and K, as shown in plan view in Figs. 10 and 11 more particularly. Attached to each end of the chain is a strip l, of leather, which extends along the inner side of the chain, as shown. On swinging forward the handle 7/ the arm D is swung up until its curved arms J are in ahorizontal position,and in such position they embrace the standard just below the plate C, as shown in dotted lines in Fig. 2 and Figs. 10 and. 11. The arm is locked in such position by the cross-pin G of the handle being at the outer end of the slot F, the parts then being substantiall y at right angles to their pivots,which causes a lock of the several parts, preventing their movements of themselves; but by operating the handle all parts are moved back to their normal positions again.

In carrying the invention into effect the procedure is substantially as follows, reference being had to Figs. 8, 9, 10, and 11: The mechanism being in its normal position, as shown in Figs. 1, 2, 3, i, 5, and 6, the upper P and its lining Q inside are placed over the upper end of the column. Then the inner sole R is introduced, as in Fig. 8, with its heel portion on top of the plate G, which supports the same. The treadle A is depressed, which pulls down the rack-bar V, swinging the arm P forward until its plate R is over the plate G and inner sole, and finally in the continued movement of the treadle the arm and its plate are pulled down so as to cause the said plate to press firmly down upon the heel of the inner sole. Then the handle M of the lever L is pressed down, which forces the pins N up through the inner sole, as shown in Fig. 8. After this the treadle is released and allowed to rise, whereby the arm P is swung back out of the way into its original position. (Shown in Figs. 1, 3, and 5.) The edge of the lining Q at the heel is then pulled by hand over the edge of the inner sole at the heel and is pressed down over the upwardlyprojecting pins, as shown in Fig. 9. The heel-counter S is then placed over the inner sole and the lining thereon, with its sides or edges inserted between the lining and upper and the bottom pressed down close to the lining. Then the handle I; is moved back, which swings up the arm D and presses closely the flexible band M around, about, and against the sides and back of the upper at the heel, which holds the upper, lining, and counter firmly between the flexible band and'standard. lVhile the parts of the shoes are so held the lever L is swung up, which pulls the pins N down, out from, and clear of the inner sole. WVith the upper, lining, and counter held, as described, by the flexible band, the corners n of the counter S held by the left hand of the operator close down upon theinner sole, and the sides of the counter compressed by said hand against the column, a tack r is driven through each corner of the counter into the lining and inner sole, as shown in Fig. 10,

which secures them together at such points. The upper and parts connected thereto can then be removed from the machine, being ready for lasting. If desired, before the upper is removed from the machine and before securing the counter by the tacks, the upper can be brought by the fingers over the counter at its corners and tacks t driven through the upper, the counter, the lining, and the inner sole at the corners of the counter, as shown in Fig. 11, which might be desired for some lasting-machines, although generally it is suflicient to secure the counter to the inner sole without the upper.

WV hat is claimed is I 1. The method of assembling an inner sole, lining and counter in connection with the upper of a boot or shoe preparatory to lasting, consisting in supporting the upper, placing the inner sole in position and holding it at the heel, pulling the lining over the edge of the inner sole at the heel and pressing it down thereon, placing the heel-counter on the lining with its upper part between the lining and the upper, holding the upper, lining and counter along their sides at the heel against the edge of the inner sole, holding the corners of the counter close down upon the lining and securing the lining and inner sole to and at each corner of the counter.

2. The method of assembling an inner sole, lining and counter in connection with the upper of a boot or shoe preparatory to lasting, consisting in supporting the upper, placing the inner sole in position and holding it at the heel, piercing the inner sole, and providing projections above the upper surface thereof, pulling the lining over the edge of the inner sole at the heel and pressing it down thereon over said projections, placing the heel-counter on the lining with its upper part between the lining and the upper, holding the upper, lining and counter along their sides at the heel against the edge of the inner sole, removing said projections from the inner sole, holding the corners of the counter close down upon the lining and securing the lining and inner sole to and at each corner of the counter.

3. The improvement in the art of manufac turing boots and shoes, which consists in taklng an upper with the lining therein, placing the inner sole inside the lining in proper position, pulling the edge of the lining over the edge of the inner sole, placing the heel-counter on the lining and inner sole at the heel with its upper part between the lining and the upper, holding the upper, lining and counter along its sides against the edge of the inner sole at the heel, and the corners of the counter close down upon the lining, and securing the lining, inner sole and counter together to and at each corner of the counter.

In testimony whereof we have signed our names to this specification each in the pres ence of two subscribing witnesses.
